 Inhabits the coasts of the Island of St. Thomas. Chemnitz. 

 Shell about two inches long, and rather more than half as 



broad ; the colour is greenish, striped with dark brown, and 



the two extreme valves, as well as the marginal triangles 



of the others, are so marked as to resemble Mosaic work. 



The margin is scaly, and formed of alternate dark green and 



white spots.

 vered with short hairs.

 In addition to the above short character, Pennant only says, 

 that the shell is five-eighths of an inch long, and Messrs.

 cinereus. The figures in the French Encyclopaedia are co- 

 pied from Pennant.
